MEANS FOR LI FTING BURNER-DRUMS.

Application filed July 7, 1919.

To all whom it may concern:

' and exact description thereof. 10

My invention relates to new and useful improvements in oil burner stoves, more particularly of that type including a burner head having a burner drum liftably mounted thereon, and the present embodiment of'my invention is associated with'a stove of the general structure shown in patent numbered 1,307,064, issued to Robert Perlick, June 17, 1919.

It is in general the object of my invention to simplify and otherwise improve the structure of mechanisms of this character, and it is more particularly my object to provide a drum lifting mechanism associated with the so called wickless type of burner head, wherein the burner head is moved vertically to vary the amount of oil supplied thereto in conjunction with a constant level source of oil supply, the lifting mechanism main taining its operative relation to the burner drum in the various positions thereof procured by fuel adjusting movement of the burner head.

A more detailed object resides in the provision of means for mounting the lifting mechanism which cooperates in a most economical manner with the bracket structure shown in my co-pending application Serial Number 284,946, filed March 25, 1919.

l/Vith the above and other objects and advantages in view, which will be apparent as the description proceeds, my invention resides in the novel features of construction, combination and arrangement of parts which will be hereinafter more particularly described and defined by the appended claims.

In the accompanying drawings:

Figure l is a view partly in side elevation and partly in section of a burner unit embodying my invention.

Fig. 2 is a rear elevational view of the lower portion of the burner unit.

Fig. 3 is a transverse sectional view on-a plane .indicated in general by the line 33 of Fig. 1.

Serial No. 309,091.

Referring now more particularly to the accompanying drawings, there is shown a burner drum of conventional nature comprising the outer cylindrical Wall 5 and con centric foraminous inner walls 6 adapted to seat on the annular burner head trough 7, said trough being supplied with oil and being supported by a depending stem 8 which is telescopically slidable in a supply pipe branch 9 upstanding from the main supply pipe 10, which, as is common in stoves of this character, extends horizontally throughout the stove and is fed from. a suitable con stant reservoir, (not shown), the level of oil supplied to the burner being indicated by the line 1 2 of Fig. 1, and it is noted that in this figure the burner head 7 is in its lowered or lighting position wherein the wick member 11 thereof is impregnated with oil. The mechanism for raising and lowering the burner head to control the supply of oil thereto includes a bracket formed of a single plate of metal intermediately bent to provide a horizontally extending arm 12 through which the branch pipe 9 is passed, and a vertically extending arm 13 having its lower end bent to also receive the 1 branch pipe 9 and to seat on the attaching bead of the branch pipe, the extremity of the arm being extended below the main supply pipe and cooperating with a strip 14 secured to the vertical arm by a bolt 14:, to clamp said vertical arm against the main supply pipe and prevent looseness of parts. The outer end of the horizontal bracket arm 12 is downturned and carries a dial plate 15 cooperating with a handle and indicator member 16 carried onone end of an operating shaft 17 which is ournaled in the bracket structure and carries a crank arm 18- at its rear end connected with a link 19 which is pivoted to the burner trough adjacent its structure with the supply stem. 8. Thus rotation of the shaft by swinging the handle 16 will raise or lower the burner head 7 and the drum 5 carried thereby.

All of the foregoing structure is shown in my said co-pen ding application, and my present invention resides in the provision of means .for' independently manually raising the burner drum 5 to space the same above the burner head when the latter is lowered, and thus permit the insertion of a match between the burner head and drum to light the wick 11. To accomplish this,

a vertical rod 20 has its upper portion slidably mounted in a foraminous plate 21- extending across the upper portion of the burner head and has its lower portion slidable in a rearwardly extending tongue 22 struck from the metal of the vertical arm 13 of the main bracket. The upper end of this rod carries a head 23 engaging a foraminous plate 24: carried by the lower portion of the inner drum wall 6. The metal which is removed from the lower laterally turned portion of the bracket arm 13 is bent outwardly and then upwardly at one side of the bracket to form a pivot ear 25 to which is pivoted the intermediate por tion of the lever 26. This pivot connection of the lever 26 is procured by a loose pivot pin passed through the lever and ear 25 and provided with an annular shoulder at the inner side of the lever, the pin being held in place by abutment against the upstanding supply pipe branch 9. I thus effect the pivot connection without the necessity of a rivetinu or similar operation, and I also provide for a ready assembly and disassembly of parts for purposes of replacement by the user of the stove, since the structure may be disassembled by removing the burner head and lifting the main bracket from the supply pipe branch on which it is mounted. The rear end portion of this lever has pivoted thereto a link 27 which is in turn pivoted to the lifting rod 20, while the forward end portion of this lever is upwardly offset from its pivot connection and terminates forwardly of the dial plate 15 in a weighted handle knob 28. Thus rocking movement of the lever 26 will procure movement of the burner drum 5 independently of the burner head, to provide the necessary spacing of the drum in lighting the burner head.

An exceedingly simple and eflicient de vice has thus been provided which may be most conveniently manipulated tolift the burner drum. It will be noted that when the burnerunit is in lowered position, as shown in Fig. 1, the forward end of the lever is disposed adjacent the bottom of the dial plate in convenient position to be grasped, and the handle 16, which forms a crank, is disposed at the opposite side of the dial plate so as not to interfere with manipulation of the lever, and as the handle 16 is swung to raise the burner drum and eventually procure the non-burning position thereof, the forward end of the lever 26 is swung downwardly so as not to interfere with this movement of the handle 16, this movement being effected by abutment of the to plate 21 of the burner head with the en arged upper portion of the rod. It will be further noted that in the swinging movement of the lever to raise the burner drum, the pivotal connection of the lever with the link 27 may move past the dead center line of the other pivots of the link and lever whereby the burner drum will be held in raised position. I

While I have shown and described a preferred embodiment of my invention, it will be appreciated that various changes and modifications of structure may be employed to meet differing conditions of use and manufacture, without departing in any manner from the spirit of my invention.

What is claimed is: i

1. In a burner of the class described, a supply pipe member, a burner head disposed above the supply pipe member and connected therewith for vertical movement, the axis of said burner head being disposed at one side of the supply pipe member, a bracket mounted on the supply pipe member, means carried by said bracket for vertically moving the burner head, an arm projecting from said bracket in the direction of the axis of the burner head, a vertical rod having slidable bearing in said bracket arm and in the burner head, a lever intermediately' pivoted to the bracket, a link pivoted to the lever and said rod and a burner drum normally seating on the burner head and engageable by the upper end of the rod to lift said drum.
